Finally, to help determine your oneWorld travel possibilities. Cathay Pacific (CX) just introduced a "Downloadable Trip Planner" available for free from www.cathaypacific.com...they developed it together with OAG and there are 3 versions, one with CX flights only, one with CX and KA, and the third one with CX, KA and oneworld flights...after you install it you will then have access to all this flight schedule information while offline, building itineraries, etc...it also includes CX / MPO / Asia Miles contact numbers worldwide, lounge information in all CX cities, etc...
Go to www.cathaypacific.com, choose "Downloadable Trip Planner" under the "Flights" category...

Since the oneWorld site no longer provides this service, it's handy to have this to check all possibilities that you have using the oneWorld Alliance.
